Artmark, 4th floor or something of Bras Basah. Their collection of Copic markers there is pretty solid, and they come in different styles too[brush tip etc].
They also sell some other stuff like brushes, and chinese ink etc and offer classes.

bras basah is the way to go~~if you go there and search, there are a LOT of shops that may prove to be quite interesting...their second hand book stores sells magazines for cheap and this is really good news if you like making collages or scrapbooking~
Also, If you're interested in getting your hands on good-quality and very affordable standard-sized photo prints, head down to 'shalom' at bras basah. you may need to wait some time for the photos to develop, though~
Oh, and I forgot to mention that the popular store there is hugea**. There's an artfriend located there too~

Daiso has a tiny section of craft supplies. (acrylic paint, poster paint, crayons, felt, an assortment of paper, and even styrofoam boards ,etc). If you take your time and look through--you might be surprised to find something really useful for your projects~ 8D
They've got two outlets, i think-- one in IMM, and the other, in plaza singapura.

you can also check out etsy.com for art & craft supplies. It's highly recommended--i've tried purchasing stuff from there and everything works fine (kinda like an ebay~). If you're a fashion student, or someone who's into jewellery design, you really need to check it out now.

Four, actually. IMM, VivoCity, Plaza Singapura, and Sembawang Shopping Center. There's also a fifth one opening up somewhere too, I think. The IMM one has the biggest selection of materials. Daiso's awesome.

I live near daiso imm and I like to go the arts section =). Recently they have different sizes of origami paper, watercolour er...pastel? bottles of acrylic (or is it poster) paint, different kinds of paint brushes and etc. Since the items are so cheap, its good for practising . One interesting thing I think they have is small canvases or even canvas notepad, to do small works with acrylic.
